Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
It was only when the triumvirate was confirmed anew
at the conference of Luca, that this affair was also arranged,
after Ptolemaeus had agreed to a further payment of 10,000 talents
(2,400,000 pounds); the governor of Syria, Aulus Gabinius,
now obtained orders from those in power to take the necessary steps
immediately for bringing back the king. The citizens of Alexandria
had meanwhile placed the crown on the head of Berenice the eldest
daughter of the ejected king, and given to her a husband
in the person of one of the spiritual princes of Roman Asia,
Archelaus the high-priest of Comana,(29) who possessed ambition enough
to hazard his secure and respectable position in the hope of mounting
the throne of the Lagids.
His attempts to gain the Roman regents
to his interests remained without success; but he did not recoil
before the idea of being obliged to maintain his new kingdom
with arms in hand even against the Romans.
